I'm an Adobe Reader novice. I've scanned a document into Adobe Reader 9 and which to delete some text from it. I can't scan the document into wordpad as it doesn't pick up the logo on the letterhead, I've also got Omnipage 15.0 but when I convert the pdf into a word document the logo isn't picked up and the document layout is confused.

First, you can't edit a document in Reader - you need Acrobat to do this.

Even in Acrobat, it will be hard to delete content from a scanned document (at least in a manner that someone else reading it cannot make out that you have done so). If you don't care about that, Redaction in Acrobat can help in deleting the content.

It's very easy task to edit text properties with Touchup text tool for me. And I also backup a pdf editing tool to edit text in PDF file with the same effect. They all have one thing in common is that makes text editing like a way of editing Word document. I don't like to convert PDF for editing, frequently I will lose formatting and get gibberish. Directly edit within PDF files is what I want.

A pdf file from scanner is an image-based file so the text of it is not independent existed and not searchable. Usually it can't be converted to a word document. An OCR program will help you extract text from a scanned pdf file. Or you can erase text on the top of the pdf file in Photoshop program.
